The range_cyclic writeback mode uses the address_space writeback_index
as the start index for writeback. With delayed allocation we were
updating writeback_index wrongly resulting in highly fragmented file.

If no_nrwrite_index_update is set we don't update nr_to_write and
address space writeback_index in write_cache_pages. This change
enables a file system to skip these updates in write_cache_pages and do
them in the writepages() callback. This patch will be followed by an
ext4 patch that make use of these new flags.

Impact: crash on module insertion with CONFIG_DEBUG_VIRTUAL
We would incorrectly BUG due to:
VIRTUAL_BUG_ON(!is_vmalloc_addr(vmalloc_addr) &&
!is_module_address(addr));
... because, at least on x86-64, is_module_address() doesn't do what

On the GM45, the amount of stolen memory mapped to the GTT was underestimated,
even though we had 508KB more available since the GTT doesn't take from
stolen memory. On the non-GM45 G4X, we overestimated how much stolen was
mapped to the GTT by 4KB, resulting in GPU page faults when that page was
accessed.
This update requires a corresponding update to xf86-video-intel to work
correctly.

Problem observed:
In IPv6, in the presence of multiple routers candidates to
default gateway in one segment, each sending a different
value of preference, the Linux hosts connected to the
segment weren't selecting the right one in all the
combinations possible of LOW/MEDIUM/HIGH preference.
This patch changes two files:
include/linux/icmpv6.h
Get the "router_pref" bitfield in the right place
(as RFC4191 says), named the bit left with this fix as
"home_agent" (RFC3775 say that's his function)
net/ipv6/ndisc.c
Corrects the binary logic behind the updating of the
router preference in the flags of the routing table
Result:
With this two fixes applied, the default route used by
the system was to consistent with the rules mentioned
in RFC4191 in case of changes in the value of preference
in router advertisements

queuecommand() looked at the remote and local node IDs before it read
the bus generation. The corresponding race with sbp2_reconnect updating
these data was probably impossible to happen though because the current
code blocks the SCSI layer during reconnection. However, better safe
than sorry, especially if someone later improves the code to not block
the SCSI layer.
